The speed of extension handling will likely be among the most important aspects of this PBX. The switching scheme as it exists right now isn't terribly bad (it's O(N+M), where N is the # of extensions and M is the avg # of priorities, but a constant search time here would be great ;-)
A new algorithm to do searching based on a 'compiled' pattern tree is introduced here, and shows a fairly flat (constant) search time, even for over 10000 patterns.
Also, using a hash table for context/priority name lookup can help prevent the find_extension routines from absorbing exponential cpu cycles as the number of contexts/priorities grow. I've previously tested find_extension with red-black trees, which have O(log2(n)) speed. Right now, I'm using hash tables, which do searches (ideally) in O(1) time. While these techniques do not yield much speed in small dialplans, they are worth the trouble in large dialplans.

Main interface to add extensions to the list for out context.
Add an extension to an extension context, this time with an ast_context *.
We sort extensions in order of matching preference, so that we can stop the search as soon as we find a suitable match. This ordering also takes care of wildcards such as '.' (meaning "one or more of any character") and '!' (which is 'earlymatch', meaning "zero or more of any character" but also impacts the return value from CANMATCH and EARLYMATCH.
The extension match rules defined in the devmeeting 2006.05.05 are quite simple: WE SELECT THE LONGEST MATCH. In detail, "longest" means the number of matched characters in the extension. In case of ties (e.g. _XXX and 333) in the length of a pattern, we give priority to entries with the smallest cardinality (e.g, [5-9] comes before [2-8] before the former has only 5 elements, while the latter has 7, etc. In case of same cardinality, the first element in the range counts. If we still have a tie, any final '!' will make this as a possibly less specific pattern.
EBUSY - can't lock EEXIST - extension with the same priority exist and no replace is set

Register a new context or find an existing one.

name | name of the new context |
registrar | registrar of the context |
This function allows you to play in two environments: the global contexts (active dialplan) or an external context set of your choosing. To act on the external set, make sure extcontexts and exttable are set; for the globals, make sure both extcontexts and exttable are NULL.
This will first search for a context with your name. If it exists already, it will not create a new one. If it does not exist, it will create a new one with the given name and registrar.
